Specification of Letters Patent.

Patented Feb. 14, 1922.

Application fi1ed September 7, 1920. Serial No. 408,590.

To all whom it may concern Be it known that I, EUGENE Hnyronn, a citizen of the United States, residing at Spokane, in the county of Spokane and State of lVashington, have invented new and useful Improvements in Road Graders and Packers-of which the following is a specifi cation.

This invention relates to improvements in road graders and packers for road making work.

It is one of the objects of this invention to provide a grader and packer composed of a plurality of sections which are not only united with each other in'a novel manner but which are also connected with Ln-equalizing bar by means serving to prevent the sections from slewing.

A further object of the invention consists in providing one of the sections with a packer and grader having a portion projecting laterally from such section and in connecting the next adjacent section in following relation with such projecting portion so that an overlapping grading and scraping result will be afforded without any break in the continuity of the road surface A further object consists in providing a main section which is reversible, top to bottom, whereby the scraping irons of either the upper or lower portion of the section may be brought into play in case the irons of one portion become warm. In connection with this reversible feature, the main sec-. tion is provided with a platform which is adapted to be altered in position in accord ance with the adjustment or reversal of said main section so that in any adjustment of the latter, the platform will be in a lower receiving position. I

A further object of this invention isto provide the device with runners which are so connected with the scraper that in certain adjustments, the scraper will be elevated by the runners out of contact with the road surface while in other adjustments the device will be lowered into contact with the road surface- The invention has many other objects and features which will be more fully described in connection with the accompanying drawings and which will be more particularly pointed out in and by the appended claims,

In the drawings,

Figure l, is a plan view of the scraper and packer with the scraper bar folded in place in the wing section. 1

Figure 2, is asectional view on line 2-2 of Figure 1. I T

Figure 3, is a longitudinal verticalsectional view on line of Figure 2. Figure 4, is a se'ctional'view on line of Figure 1. 5' Figure 5, is a plan viewof the scraper with-the scraper bar, projected, into an extended position and in draft connection with the equalizing bar.

Like characters of similar parts throughout the different .figures of the drawings.

As illustrated, 1 designates theequalizing:

or draft bar, 2 the main scraper section, 3 .the wing section and l the finisheriscraping bar. I I I Reference will now be specifically made to the main section.

Said main section has afront scraper and packer portion which is. canted with respect to the line of draft and which is of substan tially Ushape 'in' cross section, the same having an upright bite 5 and horizontally disposed limb 6, preferably of wood. The front face of the bite 5 is of sheet metal, as indicated at 7, and the scraping irons are angle irons which are designated at 8. Thus the scraper portion has upper and lower angle irons'or scraper irons eitherof which may be used dependent upon the position of the main section. It is a feature of this invention'to provide a reversible main sec tion which can be turned bottom" side up from the position shown should the lower angle iron or scraper iron become warm. This feature of the lnvention providesmeans for not only prolonging the life ofv the structure but also making it possible to continue work without stopping for-repairs. Said main section has a rear-packing por= tion 9, which is substantially at right angles to the line of draft and which may becomposed of vertical timbers 10 and horizontal timbers 11. The lowermost timber 11 will function primarily as a packer in trailing relation to the front packer portion butwill not be provided with protecting irons as in the case of the front portion which functions both as a scraper and packer. 'As the section advances, the gravel and dirt will ride above the lower scraper iron 8, against the .inetallic'facing 7, and will slew lengthwise reference designate of the protectin irons toward the left of the line of draft. Therefore, the front packer portion is protected from the excessive wear to which it would otherwise be Subjected.

The front and rear packer portions are united by a frame which consists of frame members 12, 13, 14 and 15.

a runner-way 17. As both runner-ways, and

therunners therein, are identical in structure and operation, only one need be described in detail. I a

Vith reference to Figure 3, 18 designates a runner which is of sufficient length so that its rear end 19 may bear against the front face of the rear packer portion in such a manner that the drag imposed upon the run ner, when the latter isin an operative adjustment will be prevented from straining the connecting means between the runner and the frame, the rear end of the runner impingingagainst the rear packer portion. The runner 18 has an upwardly curved portion 20 which may be surfaced with metal 21, the metallic strip 21 extending rearwardly along the upper face of the runner, as indicated at 22. A cylindrical element 23 is interposed between the members 14 and 15 and abreast of the upper face of the runner. 'A pin 24 is j ournalled in the members 14 and 15 and extends through the element 23 eccentrically to the longitudinal center thereof. Straps 25 extend about the element 23 and have their terminal ends 26 fixed on to the sides of the runner 18, there being two straps for each runner. A lever 27 ,fixed to the element 23, may be employed to turn said element 23 into a runner elevating position, as shown in Figure 3, or to theright of such position to depress the runner into anoperative position and elevate the sectionwith respectto the'road .bed or surface. This permits'of readily dragging the main section across a railroad track or bridge without resulting damage from the scraper irons. The metallic facing 22 comes into effective play when the element 23 is adjusted to elevate the scraper section and depress the runner. It will now beclear how inevitable lost mo tion will permit the drag on the runner to force the latter rearwardly so that the impinging end19 will relieve the straps 25'of what would otherwise be damaging drag strain.

The opposite ends of these frame members-are rigidly down against the flan es 28 and 30.

3 I will neirtdescribe a novel platform con struction whereby the platform may be re- ;versed upon. reversal of the main section.

Holding portions 28 and 29 are mounted upon frame member 13 and holding portions 30 and 31, are mounted upon frame member 14. These members or boards constitute pper and lower sets of inwardly projecting flanges. A set of platform boards 32, rests upon the lower flanges 28 and 30. A wedge or looking bar 33 is interposed between the upper set of flanges 29 and 31 and the platform boards 32 to effectively hold the latter The bar 33 may be secured in any desired manner by spikes 34. However, the important feature is that when the main sectionis reversed, bottom side up, from the position shown, the platform boards will be supported on the flanges 29'and 31, and the'bar will be interposed between the platform boards and the flanges 28 and 30. Thus in either adjustment, the platform will be in a properreceiving position either for supporting an operator or for receiving rock or other weight material.

Reference will next be madeto the improved wing section 3, which has a forwardly disposed packer and scraper portion 35 which is parallel with the canted portion on the main section. The canted portion on the main section projects laterally thereof, as indicated at 36, and the inner end of the wing section extends behind this projecting portion so that'the resulting overlap will avoid any break in the continuity of the finish of the road surface.- The packer portion 35 may consist of a forward member 37 having angle irons 38; The rear portion 39 is suitably secured in spaced relation to the 1105 forward member 37. A platform, comprising a plurality of boards 40 is secured mid way of the heightof the wing scraper section and their rear ends are united by timbers 41. I

By means of this central disposition of the wing platform, this wing section may be re versed without altering the relative position of the platform thereof with respect to the height thereto. It may also be stated that 1 the pins 24 are disposed centrally between the upper and lower edges of the frame members so that when the main sectionis adjusted bottom side up, the runners may likewise be reversed, the eccentric elevating and depressing mechanisin working inter- 12E changeably irrespective of the position of the main section. The wing section is shown hingedly connected with the main section by means of hinged links 42 so that the wing V section maybe tilted upwardly and then onto the main section, when desirable or advantageous. In order to take the strain oil from the hinges 42, the wing section is connected with the main section by means of a draft connection 43.

In cases where it is desirable to extend the reachof the scraper, especially where the scraper has been advanced over the road bed more than once and where it is desired to provide a finished surface and distribute all of the dirt slewed off from the wing scraper,

then, a finishing bar is employed which I will now describe in detail.

This finishing bar or section is designated at 4:4: and is pivoted between the members 37 and 39 at 45. The remaining end 46 of said bar may be suitably supported, as at t'7,wl1en in a retracted or folded position as shown in Figure 1. In- Figure 5, the scraper section is extended.

It is a novel feature of this inventionto provide not only a draft connection between an equalizing bar and the several sections of the scraper, but it is also a feature to provide such draft connection in such a manner that the imposed drag load will function to prevent slewing movement of the main or heavier section of the scraper. It is also a feature of this invention to provide a relatively heavy equalizing or draft bar so that the d aft imposed on the sections will not exercise an elevating stress tending to lift the scraper sections off from the surface, but will on the contrary, exercise a downward stress tending to hold the scraper sections in sustained engagement with the road surface. It is additionally a feature of this invention to connect the draft cables at a relatively high elevation on the scraper sections to supplement the action of the equalizing bar in "causing the draft pull to cause said sections to en age the road surface.

In d igurc 3 I have shown one draft cable 48, connected with the upper part of the scraper portion. The remaining end being connected with the equalizing bar 49 and such remaining end inclining downwardly from its connection with the main section because of the relatively heavy equalizing bar, in part, and in part by reason of the high connection of the cable with the scraper. The main draft connection is indicated at 50. A draft connection 51 is connected with the equalizing bar and with the wing section, and if the scraper or finishing section is employed, a draft connection 52 is utilized. Now it will be seen that if no further draft connections were employed, there would be a sagging backward of the adjacent ends of the wing and main sections. To counteract such defective action and to also prevent slewing of the main section I. provide draft connections or cables 53 and 54 which are connected with the main section at 55 and 56 and with the bar 49 at 57. By reason of the draft connection 43, and for other advantageous reasons such as facilitating the tilting of the wing section, the cables 58 and 54 are not required to be connected with the wing section. It will be noted that these anti-slewing cables 53 and 54 are not only disposed angularly to the line of draft, but it will also be noted that they exercise a pull on the main section in a direction angularly to that stress of the dirt which would other- 'ise act to slew the main section to the right of the line of draft. Thus I employ the usual and necessary draft cables in such a novel manner that they not only perform their functions as draft cables but they also function as anti-slewing means.

It is believed that my invention will be clearly understood from the foregoing description, and while I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import. I
